  • All game payouts and win combinations are paid out according to the pay table.
  • Only the longest win per pay way is paid out, if in sequence from leftmost to right with no gaps and in combinations according to the pay table.

  • Reel Height: In the Base game, the reels have set heights of 2, 3, 4, 5, 6 and 7 symbols, which appear in random order on each spin. The number of Pay Ways in the Base game always amounts to 5040, and in the Bonus game, reel height can be expanded (c.f. rule 12).

Big Fin Bay Bonus Features

The Wild symbol substitutes for all other symbols except the Scatter symbol.

  • Mystery Wilds: Randomly activated mystery feature in the Base game. Up to 3 reels become Wild symbols. No Scatter symbols can appear during this feature.
  • Bonus Game: 3 or more Scatter symbols on any position on the reels in the Base game trigger the Bonus game consisting of free spins. When the Bonus game is triggered, each reel with a Scatter symbol awards a random number of free spins (up to a maximum number of 6 per reel), which will be added together. The sum of these is the total number of free spins awarded for the Bonus game. For a reel awarding 4 free spins, one awarding 5 free spins, and one awarding 6 free spins will give a total number of 15 free spins. The reel heights in the spin that triggers the Bonus game will be the starting reel configuration for the Bonus game.
  • Expanding Wilds: In the Base game, a Wild symbol included in a payway win will expand to cover its entire reel. A maximum of 3 reels may contain Wild symbols on the same spin. In the Bonus game, the Wild symbol always expands. In the Bonus game, each spin where one or more Wild symbols land on the reels they will expand and trigger one respin. During the respin, the Wild symbol expands and increases the number of symbols on its reel by one, creating more pay ways. The reel size will remain expanded for the remainder of the Bonus game. During the respin, additional expanding Wild symbols can be awarded. The expansion only occurs once per symbol. The reels can expand up to a maximum of 7 symbols per reel. When a reel reaches the maximum of 7 symbols, 3 additional free spins are awarded.
  • The Bonus game is played with the same bet as the spin that triggered the Bonus game.

In the event of a game malfunction, all affected bets and pays are rendered void.

The maximum total bet multiplier for one game round is 15040. If this limit is reached, the game round will be terminated, and no additional wins will be paid out.
